The toggle clasp necklace extensions were created out of necessity for my mother in law. She commented to me that she would likes to wear turtle necks and larger sweater in the colder months however her toggle clasp necklaces get a little snug when worn over them. Or at times she would like to add a little length depending on her neckline. After listening to her needs and with some thought, the toggle necklace extender was born. Simply add the toggle and clasp to the clasp already on your necklace and whola, a more comfortable fit or added length if desired.
